In the construction of epoxy floor paint, the surface of the coating shrinks, forming beads, pinholes and other shapes and sizes, such as water sprinkled on wax paper, spots exposed to the bottom layer, is a common problem, we call this phenomenon "run oil". [cause of oil running on epoxy floor paint]
Reason 1: Oil, wax and moisture mixed in the bottom layer or paint affect the adhesion of the paint film. The surface tension of the paint film causes the film to shrink and run off oil.
Reason 2: There are non-drying thinners in the underlying coatings, such as kerosene, diesel oil, and topcoat without timely evaporation after drying.
Reason 3: The primer is too smooth, and the adhesion with the surface is less than the surface tension of the surface coating and oil run.
Cause 4: The poor wettability of the coating or the addition of too much silicone oil, are not easy to form a uniform film, easy to run oil.
[method for solving oil running off of epoxy floor paint]
1. The middle coating is carefully polished.
2. Thin coating solvent quality control is good, epoxy floor paint run-off solution to a number of as far as possible use of epoxy resin good solvent.
3, some bad medium coating contains a large amount of non-volatile plasticizer is the main reason for surface oil running.
